Check the listing for details. RARE uranium Rocks Inside Lightbulb/uranium Geology Rocks/glowing Rocks. Condition: Used, Made in United States. Listed at 170.00 USD. Rare uranium glowing, loose rocks sitting inside of a clear glass lightbulb. I Have not put it into an electrical outlet as I can only assume it’s in a lightbulb for decor. I will not be held responsible if buyer screws into an electrical source and is not satisfied or if any damage may happen. Buy on your own responsibly. However, it will sit in a glowing cabinet just like normal if want to keep for strictly decor. The rocks slightly still glow for just a little bit of time after the black light is removed. I attached a photo of the black flashlight on the rocks and then another photo Once the flashlight has been taken away, and the rocks are still slightly glowing. Measurements in photos. Message me for questions. No chips or cracks in the bulb.
